DSP kit for AUV (localization of a pinger)

Hello all.

 

My team is making a AUV (Autonomous underwater robot). I'm trying to use 3 hydrophones to locate a pinger. The pinger is a sinusoid at 40 khz.

 

I need a DSP kit suitable for this problem. It should have 3 analog inputs and enough speed to work with the signal which is sampled for 2 ms - 2s

 

So the sampling rate and memory must handle that. + Some code (filtering and angle calculations)

 

The price must not be more than 250 $

 

I was wondering about using

BF506F EZ-KIT Lite for the ADSP-BF50x Blackfin Family

do you think that one will handle it?

 

Or do you know of anyone better  ?

 

best regards.
